Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M22-6361446 is determined by the following critical parameters:

• Manufacturer series compatibility (M22 series)
• Connector type and entry configuration (Receptacle, Bottom or Top Entry)
• Mating pitch (0.079" / 2.00mm)
• Row configuration and spacing (2 rows, 0.079" spacing)
• Mounting technology (Surface Mount)
• Fastening mechanism (Push-Pull)
• Operating temperature range (-40°C ~ 105°C)
• Current rating (2A minimum)
• Material flammability and compliance standards (UL94 V-0, ROHS3)

The M22-6361742R qualifies as a substitute based on these parameters. While it features a higher position count (34 vs. 28), it maintains identical pitch, row configuration, mounting type, fastening mechanism, and environmental specifications. The contact finish differs (gold vs. tin), representing an upgrade in corrosion resistance and contact reliability.

Parameter Comparison

Engineering Selection Recommendations

The M22-6361742R is the manufacturer-recommended substitute for the obsolete M22-6361446. Selection of this alternative is supported by:

• Active product status ensuring long-term availability and supply chain continuity
• Identical mechanical and electrical specifications across all critical parameters
• Full compliance with ROHS3 and UL94 V-0 standards
• Gold contact finish providing enhanced corrosion resistance compared to tin
• Maintained 2A current rating and -40°C to 105°C operating range

The primary design consideration is the increased position count (34 vs. 28). Applications utilizing fewer than 34 positions will operate within specification, as unused contact positions do not affect connector performance. PCB layout modifications may be required to accommodate the larger footprint.

Frequently Asked Questions (FAQ)

Q: Can M22-6361742R directly replace M22-6361446 in existing designs?

A: Mechanical and electrical compatibility is maintained. The substitute features identical pitch, row spacing, mounting type, and fastening mechanism. PCB footprint adjustment is necessary due to the increased position count. Connector mating with existing plug assemblies designed for 28 positions will function correctly, as the additional 6 contact positions extend the connector length without affecting the mating interface of the original 28 positions.

Q: What is the impact of the gold contact finish upgrade?

A: Gold plating provides superior corrosion resistance and contact reliability compared to tin. This represents a performance enhancement, particularly in environments with moisture, temperature cycling, or corrosive atmospheres. No design changes are required to accommodate this upgrade.

Q: Are there packaging differences between these parts?

A: M22-6361446 packaging is not specified in available data. M22-6361742R is supplied in Tape & Reel (TR) format. Verify packaging requirements for your procurement and assembly processes.

Q: What is the mated stacking height for these connectors?

A: Both connectors support mated stacking heights of 3.6mm, 4.35mm, and 4.6mm, enabling multi-connector stacking applications without modification.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both M22-6361446 and M22-6361742R are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
